Hi! I want to change the color of the Publish Ad button, but I can't find where this style changes. Could you tell me where the color of this button changes? Thanks

You do not need to know file name (header.php) where it is, just update CSS style sheet with your modifications (style.css)

I'm looking at how different color styles are defined, but I don't know how to apply a color to this button.

 Maybe you can tell?

As example:
header .nav a.publish { background: red; border-color: red;}


Many thanks!
